Comay Power Battery Pack Salt Spray Corrosion Test Chamber

The salt spray corrosion test box for the battery pack is mainly used to detect the battery pack system. The battery pack system is placed in a salt spray box with explosion-proof function. The salt water spray test is carried out at a certain temperature for a certain period of time, and then it is stored at a certain temperature and humidity for a certain period of time. This cycle is repeated three times, and then it is stored for three days under the test standard atmospheric conditions (temperature is (23 ± 2) ℃, relative humidity is 45%~55%) to form a cycle. Repeat 4 cycles of testing to check if there are any leaks, shell ruptures, fires, or explosions in the battery pack/system.

Structural characteristics of salt spray corrosion test chamber for battery pack:
The outdoor box of the experiment adopts high-strength corrosion-resistant storage board;
The indoor chamber is made of imported PVC polyethylene board welded together;
The bottom of the test box is supported by PVC, and a 10mm thick PVC board is laid on top to support the load;
The laboratory sealing cover is made of PVC polyethylene plate welded at a top angle of 120 °, with an inverted V-shaped structure, which can effectively prevent salt solution from dripping onto the surface of the specimen;
The reagent replenishment bottle adopts a hidden water level gauge, which is easy to clean and not easy to break;
The pressure air tank is made of SUS304 # stainless steel, which has excellent insulation effect and is resistant to high pressure;
The machine base is welded with SUS304 # stainless steel;
The control box and test box are of a separate type, and the left and right structures are easy to operate

Safety protection device for salt spray corrosion test chamber of battery pack
1. When the water level is low, the power is automatically cut off, and the safety warning light device dynamically displays/beeps an alarm.

2. When the temperature exceeds the limit, the heater power supply will be automatically cut off, and the safety warning light device will dynamically display.

3. When the water level of the test drug (saline) is low, the safety warning light device dynamically displays.

4. Leakage protection function, preventing personal injury and instrument failure caused by circuit leakage or short circuit
